References
This reference list is not intended to be exhaustive, but nor is it totally constrained to the foregoing text. It does however omit references I researched that required building a cam grinding machine, although I have included references [5] and [6] which deal with making the master cam required by such beasts.
References [1] and [3] describe the manufacture of cams using a table of angle verses lift by milling. Ref [1] gives the math for calculating lift from the cam parameters and a program that will calculate tables of angle verses lift, velocity, and acceleration. Reference [2] explains what these tables mean in terms of performance and valve spring rates.
Ref [7] gives an alternate way of producing cams that appears to echo the "nibbling" method described by ET Westbury for his Sealion design. Ref [8] critiques this method and the Westbury/Chaddock figures given for the Sealion cam, then proposed Yet Another Way of milling master cams. If you decide to follow this one, be warned that an Errata appears in Vol 6, No 34, page 35.
Ref [9] contains a chapter on cam/follower properties as they relate to valve spring design. Equations for acceleration of the valve gear are provided for flat and curved flank cams. These are "reprinted by permission" from Diesel Engine Design (1950) by one TD Walshaw—who happens to be the "real" identity of the author of the reference in question!
Finally, ref [4] is typical of the treatment that can be found in any undergrad engineering text. These can often be picked up for a song in second-hand bookshops near any campus. Such treatments consider tappet geometry in more detail than [1] which is constrained to the fully tangential variety. Incidentally, the program [1] will also calculate the minimum tappet diameter to ensure fully tangential operation, while [2] analyses and critiques the cam/tappets used by several Westbury designs and LC Mason's Mastif (which earned the author a strongly worded flame from Mason's heir in the "Smoke Rings" section of a following issue of ME!)
